"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

[摘要]：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 Eu3+ ions to obtain Eu3+ centered red-orange luminescent solids via "antenna effect".
