trans-スチルベン（STB）を含む結晶性分子間化合物に関する研究の一環としてテトラシアノベンゼン（TCNB）との錯体（組成1:2）を取り上げ，320K以下で熱容量を測定した．210K付近にガラス転移を，また，280K付近に熱容量の温度依存性にわずかな異常を見いだした．ガラス転移での熱容量の跳びは単純にSTB分子の裏返りと考えるには大きすぎる．これまでに研究した化合物（STB-TCNQ，STB-TCNQF₄など）と比較・検討する．

Heat capacity of a crystalline complex STB-(TCNB)₂ (STB: trans-stilbene; TCNB: tetracyanobenzene) was measured below 320 K by adiabatic calorimetry. A glass transition was observed around 210 K. A jump in heat capacity at 210 K amounts to 10 J K^-1 mol^-1 and is incompatible with a simple reorientation of STB molecules as a possible cause of the glass transition. A small anomaly was also detected in a temperature dependence of heat capacity around 280 K. The properties of the present compound are compared with other complexes such as STB-TCNQ and STB-TCNQF₄.
