Abstract: This study describes the synthesis of 1,4-disubstitued-1,2,3-triazole benzothiadiazole derivatives (4,7-bis(1-phenyl-1H-1,2,3-triazol-4-yl)benzo[c][1,2,5]thiadiazole, BT-DC) through Cu(Ⅰ)-catalyzed “Click” reaction. The well-defined one-dimensional micro-nanowires in large quantities and with high morphological purity are successfully fabricated using a liquid phase assembly method. The length of one-dimensional microwires is more than 100 μm with the width of 500 nm~2 μm. Meanwhile, these assembles show a typical characteristic of the waveguiding behavior. Scanning near-field optical microscopy finds that the fluorescence from the BT-DC excited with an ultraviolet laser is effectively confined in the microwire structure and propagates along the one-dimensional direction. The optical loss coefficient of BT-DC is 0.61 dB/μm at 351 nm, endowing potential applications in the field of optical devices.
