π-Conjugated Macrocycles Lab
BB Group

Our Research Focus
-
We are a team of inorganic/organic material chemists focused on synthesizing novel compounds and developing innovative synthetic methodologies.
-
Our core research revolves around the design and synthesis of π-conjugated macrocyclic molecules with unique optoelectronic properties.
-
These molecules are tailored for:
-
Near-infrared (NIR) photothermal conversion therapy
-
Exploration of novel (anti)aromatic systems for diverse optoelectronic applications
-
-
We carry out multistep chemical synthesis and employ modern analytical techniques for thorough characterization.
-
Optical and electronic behavior is studied using advanced spectroscopic methods.
-
To complement our experimental findings, we perform Density Functional Theory (DFT) and Time-Dependent DFT (TD-DFT) calculations.
