Example 1 Polymer having NBD residue in side chain shown in Reference Example 1 0.0
1 g was dissolved in 3 mL of THF to prepare a polymer solution. 10, 15, 20, 30, and 40 m for NBD residue in polymer solution
ol% of Co-TPP was added to each to prepare a mixed solution of the polymer and the catalyst. This mixed solution was applied to a quartz cell and dried. The polymer film obtained on the quartz cell was irradiated with light from a distance of 30 cm using a 250-W ultra-high pressure mercury lamp, and the photoreaction rate was determined from the reduction rate of the UV spectrum (λmax 297 nm) before and after the light irradiation. . As a result, as shown in FIG. 1, NBD in the polymer film containing no Co-TPP
Residues were quantitatively converted to QC in about 7 minutes after light irradiation, but Co-T
In polymer films containing 5 or 10 mol-% PP, the isomerization reaction to NBD-QC by light irradiation and the QC generated simultaneously
Since the NBD was converted into NBD again by contact with Co-TPP, the equilibrium reached the conversion from NBD to QC at about 70-75% and 40-45%, respectively. That is, this means that heat is generated at the same time as light irradiation. Further, each polymer film was irradiated with light for 10 minutes, and the reconversion rate of QC residues in the produced polymers to NBD groups was measured. The results are shown in FIG. As is clear from FIG. 2, the higher the Co-TPP content in the polymer film, the higher the conversion rate from QC to NBD tends to be. This suggests that the polymer film containing Co-TPP is gradually converted to NBD while emitting heat after light irradiation.

Example 2 The polymer synthesized in Reference Example 3 alone and this polymer
Each film of Co-TPP was prepared on a quartz cell, and the photoreaction and the reverse isomerization reaction of QC residues in the formed potomer film were measured. The results are shown in FIG. 4 and FIG. As is clear from these results, the reaction rate of NBD reached 100% in 5 minutes of light irradiation with the polymer alone, but the polymer film containing Co-TPP reached equilibrium at the conversion rate of NBD of about 30 mol%. (FIG. 4). In addition, Co-TPP
When the polymer film after irradiation with light was left at room temperature, the generated QC residue of the polymer side chain was gradually reconverted into NBD (FIG. 5). This suggests that a functional film consisting of a polymer and Co-TPP converts light energy into heat energy.
