摘要：

In this paper we present selected members of 7 new series of bent-shaped five-ring resorcinol derivatives which are distinguished by substituents at the central core as well as at the outer rings. Depending on the kind and position of the substituents and depending on the length of the terminal chains not only have new mesophases (the C-PA phase or three unidentified B-2-like phases) been identified, but also interesting phase sequences have been observed (B-2-N; B-2-SmA; B-2-SmA-SmC; B-2-SmA-SmC-N).
