A series of carbazole cationic compounds with large two-photon absorption cross sections for imaging mitochondria in living cells with two-photon fluorescence microscopy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A series of carbazole cationic compounds based on donor- Π-acceptor (D-Π-A) structure were synthesized and characterized. They exhibit large two-photon absorption cross sections when excited by a 810 nm a laser beam, and their photophysical properties show that the intramolecular charge transfer (ICT) character is predominant. Moreover these compounds can easily pass though the intact cell membrane of living cells, amongst, 3-(1-hydroxyethyl-4-vinylpyridium iodine)-N-butyl carbazole (9B-HVC) has been proven to be capable of accumulating within the mitochondria possessing large membrane potential and imaging this organelle in living cells by means of two-photon fluorescence microscopy. At the same time usable fluorescent photos can be obtained at lower incident excitation power (5 mW) and low-micromolar concentrations (2 μM), which does not result in significant reduction in cell viability over a period of at least 24 h.
