Porphyrin Materials Research

Master's-level research on ionic self-assembly of a NiTBTAP porphyrin octacation with TPPS-based anions. The work contributed to a 2016 Tetrahedron paper showing that these charged porphyrins can form binary, ternary, and variable-composition nanomaterials.

Problem

Can an unusual octacationic porphyrin become a useful ISA building block?

The article investigated whether NiTBTAP could pair with TPPS-derived anions to form nanomaterials rather than uncontrolled aggregates. The chemistry depended on charge balance, pH, porphyrin speciation, and the identity of the TPPS anion.

Contribution

Focused Master's-level wet-lab work inside a publication-scale collaboration.

I supported synthesis and purification, collected and interpreted spectroscopic and concentration data, helped maintain repeatable lab routines, and supervised two undergraduate interns. The work was narrower than a PhD-scale software project, but it required careful experimental execution and analytical traceability.

Ionic self-assembly

Oppositely charged porphyrins forming material families.

The diagram summarizes the research logic: NiTBTAP8+ and TPPS-based anions assemble into ionic solids whose composition follows the reacting porphyrin ions.

Research behavior

What the chemistry needed to establish

Charge-driven assembly

The work used the octacationic NiTBTAP species with anionic TPPS derivatives so electrostatic balance could drive material formation in acidic aqueous conditions.

Composition checks

Reactant ratios and TPPS speciation were central to interpretation: metal TPPS complexes gave charge-neutral ionic solids, while diprotonated TPPS led to variable compositions.

Material families

The paper reports binary ionic solids, ternary ionic solids from two TPPS complexes, and binary solids with variable composition when diprotonated TPPS was used.

Practical work

Wet-lab and analysis responsibilities

Synthesis and purification

Prepared and purified porphyrin materials, keeping the bench workflow controlled enough for repeated assembly and characterization steps.

Spectroscopy

Used spectroscopic data and concentration analysis to compare reaction products and support composition interpretation.

Supervision

Supervised two undergraduate students during extracurricular internships, turning a research workflow into teachable lab routines.

Workflow

A compact research loop from reactant design to publication evidence.

The work moved through porphyrin preparation, controlled ISA reactions, purification, spectroscopic checks, interpretation against charge-neutrality expectations, and publication-ready collaboration with senior researchers.
