A series of Schiff bases 2[n] with n = 4, 6, 8, 10, 12, and 18 was prepared by the condensation of 9,9'-diaminobis(tricarbollide)Fe(II) (1b) with appropriate 4-alkoxybenzaldehydes (3[n]). Thermal analysis showed that they form nematic and smectic phases with clearing temperatures above 200 C. Comparative studies of series 2[n] and its organic analogs demonstrated that the effectiveness of bis(tricarbollide)Fe(II) in supporting liquid crystalline phases is between that of benzene and biphenyl for n 18 and lower than that of benzene for n = . The photophysical properties were investigated for the butoxy derivative 2[4] and modeled using ZINDO calculations.
