Formation of Bonded Exciplex in the Excited States of Dicyanoanthracene-Pyridine System: Time Dependent Density Functional Theory Study

Strong quenching of fluorescence was recently observed in pyridine solutions of 9,10-dicyanoanthracene chromophore. It was hypothesized that quenching may be attributed to the formation of bound charge transfer complexes in the excited states of the molecules. In this work, using time-dependent density functional calculations, we investigate the possibility of formation of bonded exciplex states between DCA and pyridine molecules. On the basis of theoretical calculations, it is proposed that a partial electron transfer occurs in the lowest excited state of the dicyanoanthracene-pyridine system which leads to the formation of bonded exciplex species and to quenching of fluorescence from dicyanoanthracene.</p

Spin Crossover in Fe(II)Ln(NCS)2 Complexes: A CASPT2 study

High-level ab initio calculations using the CASPT2 method and extensive basis sets have been performed on two 3d6 pseudo-octahedral FeII(L)n(NCS)2 complexes, Fe(NCH)4(NCS)2 and Fe(bpy)2(NCS)2. The structural properties that change during spin crossover processes, the High Spin-Low Spin energy differences, and potential energy profiles were studied. The validation of the method was performed on the model complex, Fe(NCH)4(NCS)2. Several active spaces, basis sets, and geometries were considered. The CASPT2[10,12] procedure, with CASSCF active spaces consisting of two σ ligands or- bitals with eg symmetry, five Fe-3d orbitals, and five Fe-3d′ orbitals, with medium-sized basis set is considered as an adequate method. For geometry optimization, a hybrid CASPT2/PBE0 method (the metal-ligand distance is optimized at CASPT2 level while the rest of molecule is optimized at PBE0 level) is recommended as an inexpensive alternative to obtain geometries close to the fully CASPT2 geometry.
