A new approach to the preparation of two classes of block copolymers containing liquid-crystalline segments is reported. Copolymers 1 and 2 are constituted by polytetrahydrofuran and side-chain liquid-crystalline polymethacrylate blocks, whereas block copolymers 3 consist of polystyrene and main-chain liquid-crystalline polyester blocks. The synthetic procedures leading to copolymers 1-3 are extremely versatile and can be used to prepare a great variety of block copolymer architectures. In both copolymer classes the chemically different blocks are strongly segregated in the solid and melt phases and undergo individual phase transitions. The mesophase transition temperatures of the liquid-crystalline blocks are very similar to those of the corresponding homopolymers, and their enthalpies are directly proportional to the content of the liquid-crystalline block. 相似文献

Anti-Kasha behavior has been the subject of intense debate in the last few years, as demonstrated by the high number of papers appearing in the literature on this topic, dealing with both mechanistic and applicative aspects of this phenomenon. Examples of anomalous emitters reported in the last 10 years are collected in the present review, which is focused on strictly anti-Kasha organic molecules displaying radiative deactivation from Sn and/or Tn, with n greater than 1. 相似文献

In this study, we present a full thermal characterization of antidepressant paroxetine and summarize the results for another
drug which treats depression: GW597599B. The main aim is to analyze how the thermodynamic and structural properties of these
compounds are modified when the two drugs are mixed in the solid state. We begin by putting into evidence how dehydration
and melting concur in shaping the calorimetric curves of paroxetine under different experimental conditions. Equipped with
this knowledge, we are able to interpret the thermal response of the physical mixtures paroxetine:GW597599B, in terms of partial
eutectic formation and simple superposition of contribution from the two compounds. 相似文献
