Article Synopsis
- The study focuses on BODIPY derivatives with a rigid aromatic backbone that can form self-assemblies and aggregates.
- It uses scanning tunneling microscopy (STM) and density functional theory (DFT) to directly visualize the self-assembled structures of three different BODIPY derivatives.
- The findings indicate that the arrangement of intermolecular interactions affected the structure, with some derivatives forming lamellar and staggered structures, while others took on a head-to-tail configuration based on their functional group variations.

Organelle selective fluorescent probes, especially those capable of concurrent detection of specific organelles, are of benefit to the research community in delineating the interplay between various organelles and the impact of such interaction in maintaining cellular homeostasis and its disruption in the diseased state. Although very useful, such probes are synthetically challenging to design due to the stringent lipophilicity requirement posed by different organelles, and hence, the lack of such probes being reported so far. This work details the synthesis, photophysical properties, and cellular imaging studies of two bora-diaza-indacene based fluorescent probes that can specifically and simultaneously visualise lipid droplets and endoplasmic reticulum; two organelles suggested having close interactions and implicated in stress-induced cellular dysfunction and disease progression.

Electronic address:
A new catechol-substituted monostyryl boradiazaindacene (BODIPY)-based lanthanide-free colorimetric and fluorogenic probe was developed for the sequential detection of Cu ions and dipicolinic acid (DPA), a distinctive biomarker of bacterial endospores, with high sensitivity and selectivity. In the presence of Cu ions, the blue solution of the probe changes to cyan and the fluorescence is quenched, however, the cyan color changes to blue immediately and the fluorescence is restored on contact with DPA, resulting from competitive binding of DPA that interact with Cu ions. A practical application by using Geobacillus stearothermophilus spores was further studied and as low as 1.

A novel ratiometric fluorescent probe BCB was reported for the first time for the sensitive and selective analysis of Ag based on two Boradiazaindacene (BODIPY) as both the reference fluorophore and recognition part. Upon the addition of Ag ions, a strong fluorescence emission at 570 nm from recognition BODIPY would be appeared, whereas the fluorescence of the other BODIPY at 535 nm would be a constant reference fluorescence signal. As a result, the ratio of fluorescence intensity (λ570/λ535) was changed from 0.
