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.

Brønsted acid catalysis enables the synthesis of chiral vicinal chloroamines via asymmetric protonation of catalytically generated prochiral chloroenamines. The process is highly enantioselective, with the origin of asymmetry and catalyst substituent effects elucidated by DFT calculations. The method allows access to rare heterocycle-substituted vicinal chloroamines, aziridines, and vicinal diamines
The invention relates to compounds of the formula (1) which are suitable for use in electronic devices, in particular organic electroluminescent devices.
