The five-times Olympic champion, who also failed to secure a spot in the 200 freestyle earlier in the trials, won his heat but finished 21st in the timings behind pace-setter and world champion James Magnussen in his last-chance saloon for London.
The 29-year-old's time of 50.35 seconds was his best since returning to competition in November, but was more than two seconds shy of Magnussen's and left him well outside the top 16 that will compete at the semi-finals in the evening session.
On Friday, Thorpe described his failure to qualify in the 200, his best chance for London, as a "fairytale turned nightmare", but was somewhat less dramatic as he contemplated the final nail in the coffin for his Olympic dream.
"This is... it's tough. It's hard coming to this competition and really, you know, failing in what I set out to do," he told reporters at the South Australia Aquatic and Leisure Centre.
"I'm disappointed that I really haven't been able to race in a way that's reflective of the work that I've done and how I've trained.
"But I don't regret giving this a go. Compared to how I've raced before, how I've competed and the success that I've had, this does look like doom."
"But I'm glad I was willing to put myself out there to give this a shot. I'm pleased with that part, and disappointed that it hasn't been the result that I wanted."
The headline act at the trials, Thorpe took a long time to exit the pool after winning his heat, the ninth of 12, and walked into the bowels of the arena to await his fate.
In the end there was little suspense, as almost all of the remaining swimmers smashed the 50 second mark to leave the swimmer a spectator at London, little more than a year after announcing his return to the pool.
"Thorpie's been someone I've always admired as a swimmer, so it is upsetting for him and the rest of us to do feel his pain," Olympic gold medal favourite Magnussen said.
"It would have been great to have him there in London, it's disappointing that he's not going to be there, but all I can do now is focus on my race."
On Friday, Thorpe failed to reach the final of the 200 freestyle, a result that left a packed crowd stunned and left the swimmer hugely disappointed.
The 11-times world champion's 200 bid was easily his best chance to qualify for London and although he put on a brave face after that failure, he conceded he was battling against the odds to break into the top six of the 100, which would have given him a chance of selection for the relay team.
The exit of the main attraction sucked the enthusiasm out of the crowd for the morning's remaining heats and counts as an embarrassment for Swimming Australia, which has been under fire for funding Thorpe's expensive training regime in Switzerland.
"Right from the outset it wasn't about London, per se," Australia head coach Leigh Nugent said.
"London was part of his plan with what he wanted to achieve, but that part isn't going to come to fruition. But the part of swimming beyond London is just validated is what he intends to do and he indicated that in late October."
Nugent said Thorpe has only returned to elite training in September, leaving him only six months to prepare for the trials.
"He almost got there, but he couldn't quite make it. He needs another six or seven months to then go into another highly intense training that he's used to and that his body responds to.
"So what he attempted was incredibly difficult and coming here and doing what he's done is an achievement in itself, but it's part of a bigger process. "He's (still) got it, he's such a magnificent swimmer."
Samantha Hamill qualified fastest into the semi-finals of the 200 butterfly ahead of twice-Olympic medley relay champion Jessicah Schipper, while Olympic silver medallist Brenton Rickard set the pace for the semi-finals of the 200 breaststroke.
Triple Olympic champion Stephanie Rice will bid to qualify for the Olympic 200 individual medley in the final in the evening session after already winning the 400 IM title on the opening day of the trials.
