项目摘要
In order to develop novel organic functional materials with different responding units to outer stimuli, such as light, heat, electric field, the following efforts were made in the last three years.The preparation of several organic photo-responsive materials was carried out to tune their physical properties, such as magnetic property, conductivity, or liquid crystalline property, being based on the structural change evoked by the outer stimulus of light. Although so far no organic photo-responsive conductors or liquid crystalline materials could be obtained in spite of our efforts, several organic photo-responsive spin systems could be prepared. A couple of naphthopyran derivatives with aminoxyls were found to show the changes of their intermolecular magnetic interactions with Curie-Weiss model by irradiation and the intermolecular spin-spin interactions of an azobenzene with long alkoxy group and a TEMPO radical at an end were found to be switched by irradiation from weak ferromagnet … More ic interactions with Curi-Weiss behavior to relatively strong antiferromagnetic interactions with singlet-triplet behavior and vice versa.During the course of our studies to prepare organic heat-responsive materials, a couple of spin systems with heat responsive property could be obtained. The intermolecular magnetic interactions of a heptylbiphenyl derivative with N-methylamido-TEMPO substituent was found to be changed from singlet-triplet behavior to Curie-Weiss one by merely heating over the thermal phase transition temperature, while, on the contrary, the original Curie-Weiss behavior of a cyanobiphenyl derivative with long alkoxy and a TEMPO group was coverted to singlet-triplet one by heating. Several biradical compounds with a naphthalene, biphenyl, azobenzene or azoxybenzene core and long alkoxy as well as TEMPO substituents at both their ends were found to show fairly large interermolecular magnetic interactions based on singlet-triplet model and the interactions were suggested to be originated from the unique supramolecular structural features according to their X-ray analyses.Several radical catin salts containing TEMPO radicals in anionic part and TTF derivatives in cationic part were prepared and, among them, a BEDT-TTF salt with TEMPO-sulfonate showed semi-conductive property with relatively high conductivity at room temperature together with weak ferromagnetic behavior based on 1-D Heisenberg model and their structure-property relationship could be clarified based on the X-ray crystal structure analysis.

为了开发对光、热、电场等外界刺激具有不同响应单元的新型有机功能材料,近三年来进行了以下工作。制备了几种有机光响应材料,根据外部光刺激引起的结构变化来调整其物理性质,如磁性、导电性或液晶性。尽管我们的努力还没有得到有机光响应导体或液晶材料,但我们可以制备几种有机光响应自旋体系。两个含氨基的萘吡喃衍生物的分子间磁相互作用在辐照下发生了与居里-魏斯模型的变化,具有长烷氧基和一端有TEMPO自由基的偶氮苯的分子间自旋-自旋相互作用在辐照下由弱铁磁体与居里-魏斯模型的相互作用转变为具有单重态-三重态行为的相对强的反铁磁相互作用,反之亦然。在制备有机热响应材料的过程中,我们得到了几个具有热响应性能的自旋体系。庚基联苯衍生物与n -甲基酰胺-TEMPO取代基的分子间磁相互作用仅通过加热就由单重态-三重态变为居里-魏斯态,而含有长烷氧基和TEMPO基团的三苯基衍生物则通过加热转变为单重态-三重态。基于单重态-三重态模型,发现几种以萘、联苯、偶氮苯或偶氮氧苯为核心,两端均有长烷氧基和TEMPO取代基的双基化合物表现出较大的分子间磁相互作用,并通过x射线分析认为这种相互作用源于其独特的超分子结构特征。制备了几种阴离子部分含TEMPO自由基、阳离子部分含TTF衍生物的阳离子盐,其中含TEMPO磺酸盐的bett -TTF盐在室温下具有较高的导电性和弱铁磁性,基于一维Heisenberg模型,通过x射线晶体结构分析可以明确其结构-性能关系。少
