| 抄録: | A phenylacetylene monomer, 4-(decyloxycarbonyl)phenylacetylene (DecCPA), was synthesized and polymerized by using the combined catalyst system, i.e., [Rh(norbornadiene)Cl]_2 and triethylamine, to give a yellow solid π-conjugated polymer [poly(DecCPA)] having the high molecular weight and the cis-transoidal stereo-regular main chain. Poly(DecCPA) was measured using total internal reflection fluorescence microscopy, which is a single molecule detection technique that is carried out in tetrahydrofuran solution at room temperature, and the light-twinkling of a single molecule was observed. This twinkling is the dynamic photon emission phenomenon of single poly(DecCPA) molecule that we mention specifically as resultant from the time scale-changing very slowly in the time scale of milliseconds and seconds-with changed fluorescent intensity associated with single polymer molecule conformational changing caused by the micro-Brownian motion. Although a molecular dynamics was at the picosecond time scale generally, this poly(DecCPA) molecule had the mode of the molecular motion of π-conjugated main chain did this very slowly in a second time scale was shown. |
