== | ==Objective== | ||
* | * Complete the QD syntheses begun yesterday | ||
* Attempt precipitation of JCS 4 and 5 via rotovap | |||
==Protocol== | |||
# Create 20 mM sodium sulfide solution | |||
## .024018 g of Sodium Sulfide (MW=240.18) needed for 5 mL | |||
## Used .0766 g of Sodium Sulfide used (in 10 mL) because the sample is contaminated with excess water | |||
# Add 4 mL of 20 mM sodium sulfide solution to each reaction | |||
## Allowed the mixtures to stir vigorously for 15 minutes | |||
## total synthesis time JCS 4: 11.5 hrs (including 15 minutes for Sodium Sulfide addition) | |||
## Total synthesis time JCS 5: 11.5 hrs (including 15 minutes for Sodium Sulfide addition) | |||
==Precipitation of JCS 4 and 5== | |||
# Solutions were transferred to larger, 100 mL round-bottom flasks | |||
# Each solutions was rotovapped for over 30 minutes under vacuum in a water bath of 40 °C | |||
# Resulting films were left in the round bottom flasks, covered with aluminum foil, capped, and stored in a drawer for work-up later in the week. | |||
==Notes== | |||
* JCS 4 remained a very light gray that turned dark brown once Na<sub>2</sub>S was added. | |||
* JCS 45 remained a strong yellow that turned dark brown once Na<sub>2</sub>S was added | |||
* JCS 3 remains in an ethanol-water mixture in the freezer | |||
