We have synthesized and characterized five members of a homologous series of side chain polymers of hydroxypropyl cellulose esters obtained by homogeneous esterification with 6-[4'-(ethoxycarbonyl)biphenyl-4-yloxy]hexanoic acid. Two acylation procedures were studied. One procedure involved the acid chloride derivative and the other one was the activation of(More)
In the title compound, C21H24O5, the dihedral angle between the benzene rings is 19.57 (15)°. In the crystal, the mol-ecular arrangement makes up head-to-head centrosymmetric dimers assembled by pairs of O-H⋯O bonds; this arrangement builds a graph-set ring motif of R (2) 2(8). The dimers are linked into a tape running along the b-axis direction through(More)
The title mol-ecule, C(27)H(31)NO(7), an imine derivative bearing both carbonate and allyl functionalities, was synthesized in the hope of obtaining a mesogenic polymerizable material. The allyl-carbonate arms are fully disordered over two sets of sites, reflecting a large degree of rotational freedom about σ bonds [occupancies: 0.665 (9)/0.335 (9) for one(More)
