lattices generated from the supramoleculardendrimers demonstrated that the volume of the aromatic core of the sphericaldendrimers is not dependent on the number of carbon atoms from their alkyl groups. This result facilitated the calculation of the average values of the absolute electron density of the aliphatic and aromatic domains of the sphericalsupramoleculardendrimers. The relative intensity of
effect can be effectively tuned by dispersing CSs into a commercially available RT liquid crystal matrix 8CB, which output significantly improved photothermal conversion efficiency of 63.2%. Furthermore, the photothermal can rapidly trigger the Smectic A-Nematic-Isotropic sequence transitions of 8CB doped with CSs. This work paves a way of adjusting the balance of photoluminescence and photothermal properties
Photochromic tris(phenylisoxazolyl)benzene 1 and bispyridine derivatives 2a–e were mixed in a certain ratio to generate stable gels in benzyl alcohol, 4-methoxybenzyl alcohol, and aniline. Supramolecular assembly of 1 in solution was confirmed by 1H NMR study. The Tgel value was saturated in a 2 : 3 ratio of 1 and 2c. The intermolecular hydrogen bonds OH⋯N and salt bridge O−⋯H–N+ between 1 and 2c coexisted
以一定比例混合光致变色的三(苯基异恶唑基)苯1和双吡啶衍生物2a–e,以生成稳定的凝胶。苯甲醇, 4-甲氧基苄醇, 和 苯胺。1 H NMR研究证实了溶液中1的超分子组装。所述Ť凝胶的3比:值是在一个2饱和1和2c中。分子间氢键OH⋯N和盐桥ö - ⋯11-N +之间1和2c中明显共存,这些氢键促成了凝胶网络的稳定性。2a–e烷基链的长度决定了凝胶的稳定性。凝胶的地层通过的形态过渡从动1之前和添加之后2A-E 。1的混合物和2a–e导致发达的原纤维网络,产生大量空隙,这些空隙负责固定溶剂分子。当在360nm下照射苯甲醇凝胶时,该凝胶变成溶胶。通过加热使溶胶转变为凝胶。这种凝胶到溶胶的相变是完全可逆的。
