JUGAATRONICS

Jugaatronics is a body of work that aims to address the current e-waste issues by designing consumer electronics that are repurposable, creating new electronics and objects. This project is born from the cultural practice of \u27Jugaad\u27 - the practice of repurposing everyday objects to extend their usability, a form of frugal innovation deeply embedded in my upbringing in India. Most electronic devices are often discarded at the first sign of malfunction—deemed unnecessary. My thesis highlights this throwaway culture by integrating the concept of Jugaad(repurpose) into the lifecycle of electronic products, demonstrated as a hairdryer. By showcasing potential repurposing opportunities at every stage/level of product death, Jugaatronics showcases the potential each product contains beyond its intended function and form, through small yet mighty design changes for a more sustained yet compatible lifespan of a product. This now creates compatibility with existing daily objects to create a community of people who can jugaad with ease in a system which benefits both the consumer and the earth. My thesis now encompasses an ecosystem containing an app, website and open-sourceable product compatibility system to highlight sustainability efforts along with user satisfaction. In summary, Jugaatronics is more than a design project; it is a call to action for both designers and consumers to reconsider how electronics are consumed and disposed of. By leveraging the ‘Design for Repurpose’ strategy, this project aims to demonstrate that with jugaad thinking and innovative design, we can significantly reduce e-waste and move towards a more eco-conscious future

(2,3,5,10,12,13,15,20-Octa­phenyl­porphinato)copper(II) 1,1,2,2-tetra­chloro­ethane solvate

The title complex, [Cu(C68H44N4)]·C2H2Cl4, exhibits nearly square-planar geometry around the CuII centre and the macrocyclic ring is almost planar. The porphyrin mol­ecule has an approximate non-crystallographic inversion centre (Ci), and a non-crystallographic twofold rotation axis (C 2) within the CuII–porphyrin ring plane. Further, it has non-crystallographic twofold rotation axis and mirror plane (Cs) symmetry perpendicular to the mol­ecular plane. The mol­ecular packing of the complexes and the solvent molecules shows weak inter­molecular C—H⋯π, C—H⋯Cl and C—H⋯N inter­actions, forming a clathrate-like structure

C60 1,1,2,2-tetra­chloro­ethyl­ene tetra­solvate

In the title complex, C60·4C2Cl4, the C60 mol­ecule is located on an inversion centre and there are two tetra­chloro­ethyl­ene (TCE) mol­ecules in the asymmetric unit. Both TCE mol­ecules show positional disorder, with occupancy ratios of 0.75:0.25 and 0.56:0.44. Four fullerene C atoms form short contacts [3.208 (17) and 3.223 (17) Å] with the centres of the TCE double bonds, indicating that C60–solvent inter­actions are largely π–π in nature

Substrate selectivity in the alkyne hydration mediated by NHC–Au(i) controlled by encapsulation of the catalyst within a hydrogen bonded hexameric host

Significant alterations in the substrate selectivity in the alkyne hydration reaction catalyzed by NHC-Au(i) 1 are observed as a consequence of encapsulation of the homogeneous catalyst within a hexameric resorcin[4]arene based hydrogen bonded self-assembled host

Electronic structure and molecular orientation of a Zn-tetra-phenyl porphyrin multilayer on Si(111)

The electronic properties and the molecular orientation of Zn-tetraphenyl-porphyrin films deposited on Si(111) have been investigated using synchrotron radiation. For the first time we have revealed and assigned the fine structures in the electronic spectra related to the HOMOs and LUMOs states. This is particularly important in order to understand the orbital interactions, the bond formation and the evolution of the electronic properties with oxidation or reduction of the porphyrins in supramolecular donor-acceptor complexes used in photovoltaic devices.Comment: text 11 pages, 4 figures submitted for publicatio

Molecular tweezers with freely rotating linker and porphyrin moieties

Molecular tweezers were synthesised by using a microwave accelerated alkene plus cyclobutane epoxide reaction between norbornyl appended porphyrin moieties and a diepoxide functionalised phenyl diimide spacer. The tweezers contain several rotational degrees of freedom; about the porphyrin with respect to the norbornyl linker, and between the two norbornyl backbone sections. The ability of Zn(super)II metallated tweezer 1 to complex 1,4-diazabicyclo[2.2.2]octane (DABCO) was studied by UV/Vis and ¹H NMR spectroscopy and multivariate global spectral analysis. The system was found to form a strong 1:1 intramolecular complex (1:DABCO) with an association constant of K₁₁ = 8.1 × 10⁷ M⁻¹, transforming to a 1:2 open complex [1:(DABCO)₂] with K₁₂ = 2.7 × 10⁹ M⁻² at high concentrations of DABCO.Rhys B.
