Investigating the Structure Directing Properties of Designer 1,8-Naphthalimide and Amphiphilic Sulfonate Anions and Their FeIII Thiosemicarbazone Complexes.

The FeIII thiosemicarbazone complexes of five organic sulfonate based anions are reported {[Fe(L1)2](X), where L1 = acetylthiazole 4-phenylthiosemicarbazone and X = N-(p-aminobenzenesulfonate)-1,8-naphthalimide (1), N-(m-aminobenzenesulfonate)-1,8-naphthalimide (2), N-(5-amino-1-naphthalenesulfonate)-1,8-naphthalimide (3), N-(5-amino-2-naphthalenesulfonate)-1,8-naphthalimide (4), and hexadecylsulfonate (5)}. Four complexes feature 1,8-naphthalimide based anions, known for their structure directing properties through p-based interactions, and one complex features a long chain sulfonate anion to introduce amphiphilicity to the complex to allow formation of Langmuir-Blodgett films. A full structural and photophysical study is reported for naphthalimide based anions 1-4 and complexes [Fe(L1)2](1-4), and a structural and Langmuir study is reported for [Fe(L1)2](5).
