介晶性的报道是一个dispersible配合物的金（III），是两亲性的烃和氟碳链的存在下的帐户。该复合物的全烃类似物在熔点和澄清点之间仅显示出柱状六方相，而这个新的两亲性例子在柱状矩形相和柱状六方相之间显示出双相。的性质和形成的双相进行了讨论，它被建议是一个柱状的双相形成的结果，由复杂的两亲性驱动的挫折。
The mesomorphism is reported of a discotic complex of gold(III) that is amphiphilic on account of the presence of both hydrocarbon and fluorocarbon chains. The all-hydrocarbon analogue of the complex shows only a columnar hexagonal phase between the melting and clearing points, whereas this new, amphiphilic example shows a nematic phase between a columnar rectangular phase and a columnar hexagonal phase. The nature and formation of the nematic phase are discussed and it is proposed to be a columnar nematic formed as a result of frustration driven by the amphiphilic nature of the complex.
