Three novel coordination polymers, [Zn(μ₂-HTCA)(Phen)]_n (1), {[Cd(μ₃-HTCA)(Phen)]·2H₂O}_n (2), [Mn(μ₂-HTCA)(Phen)(H₂O)]_n (3) were prepared by hydrothermal synthesis from the 4, 4', 4''-nitrilotribenzoicacid (H₃TCA) and 1, 10-phenanthroline monohydrate (Phen) with different transition metal salts, which were characterized by elemental analysis, IR spectra, powder and single-crystal X-ray diffraction and thermogravimetric analysis. The photophysical properties of the complexes were investigated by solid-state diffuse reflectance spectra, photoluminescent properties, lifetime and quantum yield. For these complexes, it was found that the band gaps follow the order: 3 ＜ 2 ＜ 1 ＜ 2.80 eV, fluorescence intensity order: 1 ＞ H₃TCA ＞ 2 ＞ 3; quantum yield order: H₃TCA ＞ 1 ＞ 2 ＞ 3; while the lifetime order: 1 ＞ 2 ＞ H₃TCA ＞ 3.

三种新的配位聚合物，[（μ锌₂ -HTCA）（phen）的] _Ñ（1），{[CD（μ ₃ -HTCA）（Phen的）]·2H ₂ ö} _Ñ（2），[锰（μ ₂ -HTCA）（Phen）（H ₂ O）] _n（3）是通过水热合成法从4，4'，4''-亚硝基三苯甲酸（H ₃TCA）和1，带有不同过渡金属盐的10-菲咯啉一水合物（Phen），通过元素分析，IR光谱，粉末和单晶X射线衍射以及热重分析进行了表征。通过固态漫反射光谱，光致发光性质，寿命和量子产率研究了配合物的光物理性质。对于这些配合物，发现带隙的顺序为：3＜2＜1＜2.80  eV，荧光强度顺序为：1＞ H ₃ TCA＞2＞3 ; 量子产率顺序：H ₃ TCA＞1＞2＞3；而寿命顺序为：1＞2＞ H ₃ TCA＞3。
