Described herin are molecules for use in organic light emitting diodes. Example molecules comprise at least one acceptor moiety A, at least one donor moiety D, and optionally one or more bridge moieties B. Each moiety A is covalently attached to either the moiety B or the moeity D, each moiety D is covalently attached to either the moeity B or the moeity A, and each B is covalently attached to at least one moiety A and at least one moiety D. Values and preferred values of moieties A, D and B are defined herein.
The introduction of perfluoroalkyl (Rf) groups into polycyclic aromatic hydrocarbons (PAHs) is a potential strategy for developing air-stable electron-acceptors that are useful for manufacturing novel n-type organic semiconductors. This paper describes a facile synthetic method for 9,13-bis[(triisopropylsilyl)ethynyl]pentacene (“TIPS-pentacene”) derivatives bearing two or four Rf groups at peripheral

Organo-metallic materials with reduced steric hindrance and the ability to aggregate are disclosed. The metal remains capable of binding additional molecules. As an example, Zn complexes that prove aggregation are provided. Such aggregation may help improve or trigger new surface properties of the materials, alone or in combination with others. In a further implementation of the present disclosure, a robust molecule that resists degradation via nucleophilic, electrophilic and radical attacks is provided. Coordinated (¾ is reduced catalytically, producing efficiently thyil radicals in spite of the extreme electronic deficiency of the catalyst.

We herein describe an unprecedented 1,2-bis(trifluoromethylation) of arynes with [CuCF3] in the presence of an oxidant DDQ. The method allows the rapid construction of a new class of 1,2-bis(trifluoromethyl)arenes in one-step from aryne precursors under mild conditions. Its synthetic utility has been demonstrated in the preparation of bis(trifluoromethylated) molecules with potential pharmaceutical

In the above formula, Q represents a divalent organic group having a substituted or unsubstituted aromatic ring; and A and A′ each independently represent an organic group. This polymer exhibits a sufficiently low dielectric constant for use as a semiconductor protection film and has the capability of forming a film at a relatively low temperature of 250° C. or lower.
