The spiro form of PCPP, poly(2,6-(3',6'-bis(2-ethylhexyloxy)-4,4'-spirobi(4H-cyclopenta[def]phenanthrene))) (spiro-PCPP) has been synthesized by Yamamoto polymerization. The PL emission spectrum in THF solution showed maximum peak at 398 nm, nearly identical with that of PCPP. PL spectrum of solid state exhibited maximum peak at 451 nm, which was red-shifted over 50 nm from that of the solution, caused by the inter-chain interaction of the polymers. The PL spectra of spiro-PCPP in THF:MeOH from 9:1 to 3:7 showed increasing peaks at 458 and 484 nm, also caused by the same inter-chain interaction of the polymers. The PL spectra of spiro-PCPP in the mixture of THF and MeOH from 9:1 to 3:7 ratios showed increasing peaks at 458 and 484 nm. With an increased ratio of the hydrophilic solvent (MeOH), the inter-chain interaction of the hydrophobic polymers was enhanced to show peaks at 458 and 484 nm. This phenomenon has the same tendency as compared to the PL spectrum in solid thin film state. The polymer LED with the configuration of ITO/PEDOT/polymer/Ca:Al showed the emission color of blue with CIE coordinate of (0.14, 0.15), which is close to those of the standard blue (0.14, 0.08). The maximum luminescence (Lmax) of the LED with spiro-PCPP was 500 cd/m2 at 13 V.
