Abstract
ABSTRACT A series of amphiphilic rodlike α-cyanostilbene mesogens bearing an α-cyanostilbene core, with one/three lipophilic and flexible alkyl chains at one end and a polar oligooxyethylene (EO) at the opposite end, have been synthesized and investigated by polarized optical microscopy (POM), differential scanning calorimetry (DSC), X-ray scattering, scanning electron microscope (SEM), UV-vis spectroscopy and photoluminescence as well as CV measurements. These compounds can self-assemble into photoresponsive liquid crystalline phases and possess AIEE characteristics, mechanofluorochromic properties and Fe3+ recognition properties. The conductivity of the lithium cation complex was also measured to be 2.6 × 10−7 S m−1. Such compounds can be considered as a kind of multifunctional materials.
摘要合成了一系列具有α-氰基二苯乙烯核的两亲性棒状α-氰基二苯乙烯介晶，一端有三条亲脂性和柔性的烷基链，另一端有极性低聚氧乙烯（EO），并用偏光显微镜（POM）、差示扫描量热法（DSC）、X射线散射、扫描电子显微镜（SEM），紫外可见光谱和光致发光以及CV测量。这些化合物可以自组装成光响应液晶相，并具有AIEE特性、机械荧光变色特性和Fe3+识别特性。锂-阳离子复合物的电导率也测得为2.6×10−7 S m−1。这些化合物可以被认为是一种多功能材料。
期刊介绍：
Providing a common forum for all soft matter scientists, Soft Materials covers theory, simulation, and experimental research in this rapidly expanding and interdisciplinary field. As soft materials are often at the heart of modern technologies, soft matter science has implications and applications in many areas ranging from biology to engineering.
Unlike many journals which focus primarily on individual classes of materials or particular applications, Soft Materials draw on all physical, chemical, materials science, and biological aspects of soft matter. Featured topics include polymers, biomacromolecules, colloids, membranes, Langmuir-Blodgett films, liquid crystals, granular matter, soft interfaces, complex fluids, surfactants, gels, nanomaterials, self-organization, supramolecular science, molecular recognition, soft glasses, amphiphiles, foams, and active matter.
Truly international in scope, Soft Materials contains original research, invited reviews, in-depth technical tutorials, and book reviews.
