Self-assembly of ZnX 2 (X − = ClO 4 − and CF 3 SO 3 − ) with naphthalene-2,6-diyl-diisonicotinate (L) gives rise to the 2D sheet structures with composition of [ZnL 2 (H 2 O) 2 ](ClO 4 ) 2 ·H 2 O and [ZnL 2 (CF 3 SO 3 ) 2 ], respectively. [ZnL 2 (H 2 O) 2 ](ClO 4 ) 2 ·H 2 O is packed in an interpenetration mode, whereas [ZnL 2 (CF 3 SO 3 ) 2 ] exists as a simple 2D network in the crystalline solid state. These two crystals have been employed as hetero-catalysts for transesterification reactions of phenylacetate with alcohol. The catalytic effect on the transesterification reaction shows the order of [ZnL 2 (H 2 O) 2 ](ClO 4 ) 2 ·H 2 O > Zn(CF 3 SO 3 ) 2 > [ZnL 2 (OTf) 2 ] > Zn(ClO 4 ) 2 , which indicate that molecular packing is an important factor in the catalysis.

深入了解分子堆积对锌(II)配位聚合物的酯交换催化作用

ZnX 2 (X - = ClO 4 - 和CF 3 SO 3 - )与萘-2,6-二异烟酸酯(L)的自组装产生具有[ZnL 2 (H 2 O)组成的2D片状结构) 2 ](ClO 4 ) 2 ·H 2 O 和[ZnL 2 (CF 3 SO 3 ) 2 ]。[ZnL 2 (H 2 O) 2 ](ClO 4 ) 2 ·H 2 O 以互穿模式填充,而[ZnL 2 (CF 3 SO 3 ) 2 ] 在结晶固态下作为简单的二维网络存在。这两种晶体已被用作苯乙酸酯与醇的酯交换反应的杂催化剂。对酯交换反应的催化作用表现为[ZnL 2 (H 2 O) 2 ](ClO 4 ) 2 ·H 2 O > Zn(CF 3 SO 3 ) 2 > [ZnL 2 (OTf) 2 ] > Zn (ClO 4 ) 2 ,这表明分子堆积是催化的重要因素。
