Supplementary Dataset for Thesis: Bridging the Gap in Sustainable Continuous Chemicals Manufacture: Integrating Upstream Synthesis and Downstream Crystallisation - Chapter "Thermochromics"
The dataset includes the videos recorded for hot-stage microscopy measurements of cocrystal systems: 4-bromo-2-methylaniline:3,5-dinitrobenzoic acid (4Br2MA:35DNBA) and 4-iodo-2-methylaniline:3,5-dinitrobenzoic acid (4I2MA:35DNBA) isolated from slow evaporation and antisolvent crystallisation (batch and flow) experiments which is discussed in the Thesis Chapter.
The video demonstrates the co-crystals systems colour changing properties and phase transition behaviour in response to temperature as well as the co-crystal melting points.
TC1.8 and Cc4 concern 4I2MA:35DNBA cocrystals and TC3.1, TC3.4, TC4.1 TC4.2, TC4.3 and TC4.4 correspond to 4Br2MA:35DNBA

Data collection method:
Real-time analysis of phase transitions was conducted using a Mettler Toledo FP82 hot stage equipped with a Leica DM1000 microscope. A small amount of sample was placed onto a glass slide and transferred to the hot stage chamber. The sample was then subjected to a temperature program using the FP90 Central Processor. The microscope was equipped with an Infinity 2 camera to record any changes in real time. The Studio86Designs software was used capture the video. Playback of the videos was carried out using Studio Player. In a typical experiment, a sample is heated at 5 C per min from a start temperature of 35 C until the sample has visibly melted. The video would be logged and played back to observe any visible changes in colour; a loss of crystallinity; solvent precipitation or a melting point over a specific temperature range. In samples subjected to water, 20 uL deionised water was added to the sample on the glass slide before being subjected to hot stage microscopy.
Technical details and requirements:
Playback software capable of reading avi. files - e.g. VLC media player
