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.

In this paper, a green and facile protocol was described which was efficient for synthesis of benzimidazolesusingnano‐Fe3O4 catalyst with continuous bubbling of air as the oxidant in PEG‐400/H2O aqueoussystem at roomtemperature. This protocol afforded the target products in good to excellent yields and the catalytic system could be recycled and reused without significant loss of catalytic activity
