Chain-wide learning for inclusive agrifood market development : a guide to multi-stakeholder processes for linking small-scale producers to modern markets

This guide provides a set of concepts and analytical tools for finding ways to better link small-scale producers to the modern markets associated with today’s largescale supermarket retail and wholesale operations. It is has been developed through iterative testing with partners in several organisations and countries. The guide is a product of the Regoverning Markets Programme, a multi-agency programme to generate strategic information and anticipatory policy advice on small-scale producers in these fast changing markets

Coplanarity by hydrogen bonding in well-defined oligoheterocycles

(Hetero)aryl-aryl coupling for covalent bonding and intramol. hydrogen bond formation for establishing the secondary structure have been united to design and construct well-defined, functionalized macromols. The suitability of azaheterocyclic units to realize this concept is exemplified by star shaped discotic liq. cryst. compds. and ladder-type conjugated copolymers. A review with >40 ref

pi-Conjugated oligomers and polymers with a self-assembled ladder-like structure

A series of alternating polymers and well-defined oligomers, composed of 2,5-linked pyrazines and N,N'-diacylated phenylene-1,4-diamines were prepd. using the Stille cross-coupling. The presence of N-hydrogen bond acceptors and N-hydrogen bond donors in adjacent units induces intramol. hydrogen bonding and hence leads to spontaneous formation of a ladder-type structure in which the arylene units tend to become coplanar. Self-assembly of the ladder structure in soln. is convincingly demonstrated by NRM- and IR-spectroscopy. The acylation of the ortho-amine functionalities with lipophilic groups leads to strong hydrogen bonding and improve soly. These large ortho-substituents do not disturb the p-delocalization of the syste
