"Click-Fluors": synthesis of a family of pi-conjugated fluorescent back-to-back coupled 2,6-bis(triazol-1-yl)pyridines and their self-assembly studies

J Org Chem. 2010 Jul 16;75(14):4852-5. doi: 10.1021/jo100598q.

Abstract

This paper presents an eight-step synthetic method for the preparation of a series of new back-to-back coupled 2,6-bis(triazol-1-yl)pyridine (btp) molecules (L1-L3). These L1-L3 molecules displayed fluorescent emission at 381, 381, and 457 nm, respectively. We also demonstrated the self-assembly of these fluorescent molecules with Eu(3+) ions to obtain Eu(3+) centered red-orange luminescent solids via "antenna effect".
