Strong circular dichroism (CD) is observed for gelled solutions of a PAO substituted with homochiral S-2-methylbutoxy side chains on the central phenylene unit. The CD is attributed to formation of a chiral supramolecular aggregate structure. The PAOs are phosphorescent at ambient temperature in solution and in the aggregate/gel state. The phosphorescence band is blue-shifted ca. 20 nm in the aggregate/gel
具有一般结构反式,反式-[(RO)3Ph-C[三键]C-Pt(PMe3)2-C[三键]C-(Ar)-C[三键的铂炔低聚物系列(PAOs)键]C-Pt(PMe3)2-C[三键]C-Ph(OR)3],其中 Ar = 1,4-亚苯基、2,5-亚苯基或双-2,5-(S-2 -甲基丁氧基)-1,4-亚苯基和 R = n-C12H25 凝胶烃溶剂,浓度高于 1 mM。凝胶化是热可逆的(T(gel-sol) 大约为 40-50 摄氏度),它发生是由于 PAO 的聚集导致形成纤维网络,通过 TEM 成像观察到干燥的凝胶。详细探讨了聚集/凝胶化对 PAO 光物理特性的影响。聚集导致低聚物吸收光谱发生显着蓝移,并且这种转变归因于发色团的 H 聚集引起的激子相互作用。对于中心亚苯基单元上被同手性 S-2-甲基丁氧基侧链取代的 PAO 的凝胶溶液,观察到强圆二色性 (CD)。CD归因于手性超分子聚集体结构的形成。PAOs

Three DPAF derivatives DPAF-n (n = 8, 12, 16) with identical central aromatic cores and different lengths of flexible alkyl chains have been synthesized and employed as building blocks to fabricate luminescent twisted wires.
Dipyrrolylpyrazole (dpp) derivatives possessing an aryl ring at the pyrazole 4‐position were synthesized. Upon protonation, modified dpp derivatives formed a variety of assembled structures through complexation with carboxylates, as observed by single‐crystal X‐ray and synchrotron XRD analyses. In particular, the complexation of protonated dpp species possessing long alkyl chains with dicarboxylates
