Abstract

Structural and sensing characteristics of zinc(II) 2,11,20,29-tetra-tert-butyl-2,3-naphthalocyanine (ZnNc(tBu)₄) films are studied. The chemiresistive sensing response of ZnNc(tBu)₄ films to ammonia in concentrations below the threshold limit value (TLV) in the working zone′s air is considered for the first time. It is shown that the annealing of ZnNc(tBu)₄ films in air at 250 °C for 3 h causes a phase transition to a stable high-temperature β-phase, increases the crystallite size, and enhances the sensing response to ammonia by 40-45 times, depending on its concentration.

四叔丁基取代锌（II）萘菁薄膜的结构与传感性能

研究了锌（II） 2,11,20,29-四叔丁基-2,3-萘菁（ZnNc(tBu)4）薄膜的结构和传感特性。首次考虑了ZnNc(tBu)4薄膜对工作区域空气中低于阈值（TLV）浓度的氨的化学传感响应。结果表明，ZnNc(tBu)4薄膜在空气中250℃下退火3 h后，相变为稳定的高温β相，晶粒尺寸增大，对氨的传感响应提高了40 ~ 45倍，随氨浓度的变化而变化。
