Poly 1189 III

The 19-mer sequence must not contain four or five consecutive T or A residues, because this would act as a premature termination of transcription signal for the poly III complex. 

In the same work, norbornene derivatives with a (4 -methoxy-biphenyl-4-yl)-oxy mesogen linked by an ether group Ill-n (n=4-6, see Fig. 4) were synthesized. Surprisingly, in contrast to ester-hnked polymers (I-n) [38], all of the poly-(III-n) polymers gave highly crystalline polymers (Table 1) caused by side chain crystallization, even in polymers with relatively short spacers ( =4-6).
