Increasing the modified time from 0 day to 4 days, the surface contact angle indicated by glycerol increased from 88.7° to 99.0°, indicated by water from 54.2°to 69.1° and indicated by diazomethane declined hum 40.0° to 31.9°.

结果表明，改性0-10d的木材吸水率从138.4%下降到111.1%；木材分别经过1d、2d和4d的硅烷化改性，甘油表面接触角从未改性时的88.7°上升到99.0°，蒸馏水表面接触角从54.2°上升到69.1°，二碘甲烷则从40.0°下降到31.9°。

Chapter two: Using 5-(4-aminophenyl)-10,15,20-triphenylporphyrin as thestarting compound, the classical diazotization of aniline and the resulting reaction ofdiazo salts were applied to porphyrin for the first time, and a series of asymmetriclysubstituted meso-tetraarylporphyrins including 5-(4-chlorophenyl)-10,15,20-triphenylporphyrin, 5-(4-iodinphenyl)-10,15,20-triphenylporphyrin, 5-(4-cyanophenyl)-10,15,20-triphenylporphyrin, 5-(4-bisphenyl)-10,15,20-triphenylporphyrin and 5-(4-hydroxylphenyl)-10,15,20-triphenylporphyrin were synthesized.
