通过使用浓硫酸对2,2’-二羟基-1,1’-二萘的磺化与成环反应得到一种新配体,7-氧杂-二苯芴-3,11-二磺酸。通过水热方法得到了它的两个化合物,[CdL(bipy)2(H2O)][Cd(bipy)2(H2O)2]·L·H2O(1)和[CdL(phen)2(H2O)]·5H2O(2),并通过X-射线单晶衍射分析进行结构表征。化合物1以P1空间群结晶,晶胞参数为a=1.2055(6),b=1.5764(8),c=1.9545(10)nm,α=75.755(9),β=88.093(10),γ=89.035(10)°。化合物2以P21/c空间群结晶,晶胞参数为a=2.1040(7),b=1.3580(4),c=1.4289(5)nm,β=94.543(6)°。在化合物1中,有两个独立的镉髤离子不对称单元,在其中镉(1)离子和两个联吡啶上的四个氮原子,磺酸配体上的一个氧原子及一个水分子配位;镉(2)离子和两个联吡啶上的四个氮原子和两个水分子配位。两种固体化合物在室温下均显示强的蓝色荧光。
A new ligand, 7-oxa-diphenylfluorene-3,11-disulfonic acid, was obtained by sulfonation and cyclization of 2,2’-dihydroxy-1,1’-dinaphthalene with concentrated sulfuric acid . Two of its compounds [CdL (bipy) 2 (H2O)] [Cd (bipy) 2 (H2O) 2] · L · H2O (1) and [CdL (phen) 2 ] .5H2O (2) and structural characterization by X-ray single crystal diffraction analysis. Compound 1 crystallizes in the P1 space group with unit cell parameters of a = 1.2055 (6), b = 1.5764 (8), c = 1.9545 (10) nm, α = 75.755 (9), β = 88.093 89.035 (10) °. Compound 2 crystallizes in the P21 / c space group with unit cell parameters of a = 2.1040 (7), b = 1.3580 (4), c = 1.4289 (5) nm and β = 94.543 (6) °. In compound 1, there are two independent cadmium ion asymmetric units in which cadmium (1) ions and four nitrogen atoms on two bipyridyls, one oxygen atom on a sulfonic acid ligand, and one water molecule The two nitrogen atoms of two cadmium (2) ions and two bipyridyls coordinate with two water molecules. Both solid compounds show strong blue fluorescence at room temperature.
